LT1965IDD-2.5#TRPBF Low Dropout Regulator

The LT1965IDD-2.5#TRPBF is a high-performance low dropout linear regulator (LDO) from Linear Technology, now part of Analog Devices, designed to deliver continuous output current up to 1.1A with a dropout voltage of only 300mV at full load. This component is ideal for applications that require a highly stable and low noise power supply while operating close to the input supply voltage.

This LDO is optimized for fast transient response and is stable with output capacitors as low as 10μF, making it suitable for modern high-speed and high-density circuit designs. The low output noise of only 40μVRMS over a 10Hz to 100kHz bandwidth ensures that sensitive RF and analog circuits have minimal interference, which is critical for maintaining signal integrity in precision applications.

The LT1965IDD-2.5#TRPBF operates with an input voltage range from 1.8V to 20V, providing a fixed output voltage of 2.5V, which is ideal for powering low voltage logic and sophisticated data converters in mixed-signal systems. The device features a wide temperature range, ensuring reliable performance in both commercial and industrial environments.

Additional features of this LDO include over-current and over-temperature protection, which safeguard the device and the load from extreme conditions. The LT1965IDD-2.5#TRPBF also offers an adjustable soft-start capability that can be used to limit inrush current during startup, providing additional protection for sensitive loads.

The regulator is available in a low-profile (0.75mm) 8-lead DFN package with an exposed pad for enhanced thermal performance. This package is suitable for space-constrained applications and allows for efficient heat dissipation, ensuring the regulator maintains its performance across its entire operating range.

With its robust set of features, the LT1965IDD-2.5#TRPBF is an excellent choice for high-performance power supply designs in telecommunications, portable electronics, microprocessor supply, and post-regulation applications. Designers can rely on the precision and reliability of this LDO to deliver a clean and stable voltage source in their electronic products.
